FREDERICK M. WHYTE, OF TARRYTOWN, NEW YORK.

GAR-END CONSTRUCTION.

To all whom it may concern:

Be it known that I, FREDERICK M. WHYTE, a citizen of the United States of America, residing at Tarrytown, in the county of Westchester and State of New York, have invented certain new and useful Improvements in Car-End Constructions, of which the following is a specification, reference being had therein to the accompanying drawings. v

The invention relates to car body con structions of that type employing metal plates, and it-is the object of the invention to secure with a minimum weight of metal the maximum strength and durability, and also a construction which is easily manufac tured and forms a thorough weatherproof covering. I In the present state of the art various constructions have been devised in which metal plates have been bent, pressed or otherwise fashioned and secured to' each otherto form the constituent elements of a truss; but in all of these prior structures there have been certain defects which it is the object of the present invention to overcome. For instance, where the plates arebent to form corrugations there is difliculty in forming a satisfactory weatherproof joint 'attheends of suchcorrugations. Alsowhere the corrugations are of a rounded cross-section the metal is not so disposed as to be highly efficient in forming a truss. Where ribs or panels terminating inside the margin of the sheet are pressed therein, this requires relatively soft metal to successfully produce the required depth of rib, and by drawingor stretching certain portions'of the section reduces the s trength; also the cost of manufacture is increased. Where the structure is built up from a plurality of sheets of thin gage metal 'the 'amount of surface exposed to corrosion is" greatly increased, while a thinner gage of metal decreases the length of life; 1 4

To overcome these defects some of the features of'my invention are: first, a single ply plate, which is cold fashioned, 'andtherefore can be manufactured at small cost 1n com- Specification of Letters Patent. Patented July 12, 1921" Application filed October 8, 1919. Serial No. 329,226.

parison with hot pressed plates; fourth, a

plate having the greater portion of its area dlsposed in two separated and substantially parallel planes with connecting portions for carrying the stresses from one plane to the other; fifth, a plate having its major por tion in the two planes, as just described,

with another portion bent into a plane transverse to the first-mentioned planes to form a corner construction; sixth, a construction which can be formed from a rectangular blank andmaintains its rectangularity when fashioned so as to require no trimming; seventh, a plate having 'a ribbed. corner, or angle bend, formed without material draw ing or stretching of the metal.

Inthe drawings I have shown my invention as applied to a construction of metallic end of the car, being of sufficient length to 7 turn corners and overlap the sides of the corner posts. The metal in the body of the plate is mainly distributed in two planes parallel to and separated from each other, while the continuity is maintained by zigzagging from one plane to the other. This will form a series of panels alternately in the difierent planes, the width of said panels and the angle of the transversely extending connecting portions being selected'to place the maximum amount of'metal in work at points farthest removed from the neutral axis. Specifically, the width of the panel is preferably from four to six times the depth of distance between the two planes and the angle of the transverse portions is preferably approximately 60 to the parallel. planes. 7

With. the plate as thus far described, it would be difficult to form a weatherproof joint at the ends thereof, nor would it be possible to turn a corner without distortion, because of the greater length of profile in the outer plane over that in the inner plane. I have, however, devised a construction in which the ends of the plate may be bent at right angles without drawing or distorting the metal but merely bending the same. The principle underlying the construction is 'illustrated'in' Fig. A in which A and B are alternate panels connected by the inclined portions C, and D is a portion of the plate at the. end thereof extending transversely to the planes of the portionsA and B and preferably at' right angles thereto. In forming the paneled portion one dimension of the original blank will be materially shortened and to compensate for this in the transverse portion D without any drawing or stretching of the metal, there is providedone or more ribs E. To avoid drawing or stretching of the metal in thelongitudinal plane thereof, the corners are so fashioned that all horizontal sections are of substan tially equal length from one; end of the plate' to theother. Thus as shown, the panels B are connected with the aortion D by the obliquely inclined portion l3 and a fiat portion B which has an angle-bend therein. The inner panels A are connected with the portionD by a rounded bead A and the ribs are arranged opposite the obliquely inclined portions This will make the profile; length of the various horizontal cross-sections of: the blank equal and the connecting portions of the metal are also fashioned in such a manner that all vertical cross-sections are of the same length of profile. Consequently, the blank may be pressed without any material drawing or stretching. of the metal and the marginal portions ofthe blank will maintain their original angular, relation, although the overall. dimensions are shortened.

The plates as above described can be readily cold pressed and when applied to a car-endwill extend horizontally from cornerto corner thereof, the fiange portions D overlapping the corner posts. To complete a weatherproof joint it is only necessary to close the ends of the ribs E which may be accomplished by inserts 1 welded or otherwise secured. The plate is bolted or otherwise secured to the corner posts and woodenstrips J may be placed in the spaces formed between the outer and. inner panels to which the lining K of the car may be attached. WVhere' the plates are used for the sides of the car or in other locations, they may be modified as necessary, but the same principle of construction is maintained by fashioning and trussing without materially drawing the metal.

To facilitate the pressing of the sheet and theequalizing of the profile lengths, the

' inclined portions 0 are preferably connected to the panels A and B by slighter inclines C and C fashioned portions maintaining a substantially uniform length of section in all parallel intersecting planes.
